Sorry for those with broader interests,
but this page contains almost only mathematical stuff.
If you're interested in other questions, mainly on research and higher
education in France, you can check my old
blog (not maintained at
this point, maybe I'll come back to it some time sooner or later).

You can also find here a list of nice little open
problems, as well as a list of nice previously
solved problems. Those lists are extremely short for the moment but
they might eventually grow. I hope somebody has some fun thinking about
them.
